Dissociation of a Bipolar Prosthesis after Right Hip Hemiarthroplasty
نویسندگان
چکیده
We report the case of an 84-year-old woman with a dissociated bipolar component of her right hip hemiarthroplasty. Dissociation of components is a rare but increasingly recognized consequence of modular componentry. Radiologists should be aware of the distinction between dislocation of a prosthesis and dissociation of its bipolar components, and be able to describe these complications accurately in their interpretations.

Comparative study in surgical outcome of intracapsular fracture neck of femur in active elderly patients treated with hemiarthroplasty with Austin Moore's and bipolar prosthesis.
Fracture neck of femur is most commonly encountered fractures in elderly population. Hemiarthroplasty is generally considered to be the treatment of choice in most active elderly patients. However, there is inadequate evidence to support the choice between unipolar or bipolar prosthesis. This study was conducted to analyze the outcome regarding pain, hip function, complication and acetabular er...
متن کاملComparison of Intertrochanteric Fracture Fixation with Dynamic Hip Screw and Bipolar Hemiarthroplasty Techniques
Background: At present, there is no consensus on an appropriate treatment modality for intertrochanteric fractures in the elderly with background diseases. The aim of the present study was to compare treatment outcomes of intertrochanteric fractures reduced with dynamic hip screws (DHS) and bipolar hemiarthroplasty in elderly patients with background medical conditions. Methods: In this randomi...
متن کاملThe Conversion Rate of Bipolar Hemiarthroplasty after a Hip Fracture to a Total Hip Arthroplasty
BACKGROUND Bipolar hip hemiarthroplasty is used in the management of fractures of the proximal femur. The dual articulation is cited as advantageous in comparison to unipolar prostheses as it decreases acetabular erosion, has a lower dislocation rates and is easier to convert to a total hip arthroplasty (THA) should the need arise. However, these claims are debatable. Our study examines the rat...
متن کاملProximal migration of a bipolar prosthesis into the innominate bone.
Bipolar hemiarthroplasty of the hip joint has been used for the treatment of femoral neck fractures and osteonecrosis of the femoral head.1-2 This prosthesis originally was believed to decrease shear stress on the acetabular cartilage, resulting in decreased migration.3,4 However, osteolysis of the acetabulum and migration of the head have been reported after bipolar hemiarthroplasty.5-7 This a...
متن کاملDisplaced intra-capsular neck femur fractures in elderly: Austin Moore’s prosthesis or Cemented Modular Bipolar Prosthesis
Introduction: With various options available like unipolar, bipolar hemiarthroplasty or total hip arthroplasty, it would be wise to choose hemiarthroplasty as it is a procedure with a short operating time with lesser morbidity for elderly patients with displaced intra-capsular neck femur fractures .This study is aimed primarily at comparing the functional results obtained after a hemiarthroplas...
